Radiation measurements made during the the second half of August2008 during a long ice station from the ice breaker Oden. Each measurement type (incident, reflected, etc) was made with a different TriOS Ramses spectroradiometer. See Nicolaus et al., 2010, CRST 62(1) 14-28 doi:10.1016/j.coldregions.2010.03.001, for more information. These sensors are known to have calibration issues at the longest and shortest wavelengths for which data are reported; we recommend using only data from about 350 to 920 nm. No significant quality control has beendone to these data.
